Abstract
The present invention relates to re-compounded enzyme preparation and its application in cotton fabric treatment, and is especially one bath and two step enzyme process for pre-treating cotton fabric. Alkaline pectase, cellulase, alpha-amylase, PVA degrading enzyme, proteinase, lipase, xylanase and sugar oxidase are first re-compounded, and the re-compounded enzyme preparation is then used in the one bath and two step enzyme process for pre-treating cotton fabric. The process includes the first desizing and boiling off step in the treating bath at 55 deg.c and pH 8.0 for 60-90 min, with the sugar oxidase reacting with the desizing product to produce hydrogen peroxide; and the second fabric bleaching step with the enzyme process generated hydrogen peroxide at 95 deg.c and pH 11.0 for 60-120min. The present invention has low power consumption, short technological process and environment friendship, and may be used to replace chemical process.
Description
Technical field
A kind of usefulness one one bath two-step enzyme process carries out the method for cotton pretreatment, relates to composite enzyme preparation and the applied technical field in cotton pretreatment technology thereof.
Background technology
With enzyme COTTON FABRIC is carried out destarch, kiering, bleaching respectively and handles because action temperature and, the processing time is long than traditional handicraft, cost is high.The enzyme preparation that is used for destarch, kiering has catalytic activity under identical condition, be used for the processing of COTTON FABRIC after composite, can realize that the merging of multiple tracks technology is carried out.With an one bath two-step enzyme process COTTON FABRIC is carried out pre-treatment, can shortened process and processing time, thus reduce cost, improve the efficient of enzymatic treatment.
Summary of the invention
The purpose of this invention is to provide the method that a kind of usefulness one one bath two-step enzyme process carries out cotton pretreatment, solve the drawback of present COTTON FABRIC chemistry pretreatment process high energy consumption, high pollution, fabric is not caused serious damage simultaneously.
Technical scheme of the present invention: the method for carrying out cotton pretreatment with an one bath two-step enzyme process, be the destarch of COTTON FABRIC enzyme process, enzyme process kiering and enzyme process to be bleached three road technologies foreshorten to an one bath two-step and carry out, handle to bathe and consist of: composite enzyme preparation 0.3～1.5g/L, BHJ-1 high-efficiency refining agent 2～5g/L, waterglass 3～10g/L and sodium ethylene diamine tetracetate 3～5g/L; COTTON FABRIC is 1: 20 with handling the mass ratio of bathing, treatment conditions are that the first step at first will be handled bath temperature and be controlled at 55 ℃, pH8.0, effect 60～90min, the destarch of COTTON FABRIC and kiering are carried out simultaneously under this condition, carbohydrate oxidase is that substrate generates hydrogen peroxide with the destarch product simultaneously, is used for the bleaching of next step fabric; Second step will be handled bath temperature and be transferred to 95 ℃, and the pH value transfers to 11.0, and effect 60～120min carries out the bleaching of COTTON FABRIC; Described composite enzyme preparation is alkaline pectase 18%～23%, cellulase 10%～15%, α-Dian Fenmei 9%～12%, PVA digestive enzyme 10%～14%, proteinase 8 %～12%, lipase 10%～13%, carbohydrate oxidase 12%～14% and zytase 8%～13%.
Beneficial effect of the present invention: with biology enzyme COTTON FABRIC is carried out destarch, kiering, bleaching pre-treatment, the action condition gentleness does not cause damage to fabric, and energy consumption is low simultaneously, environmental friendliness, and fabric treating can satisfy the processing request of later process.Use the PVA digestive enzyme COTTON FABRIC is carried out destarch, can realize that the PVA slurry at the complete biodegradable in destarch stage, has significantly reduced the discharging of PVA waste water; With enzyme COTTON FABRIC is carried out kiering, the pectic substance that alkaline pectase can the degradation of fibers top layer is removed wax simultaneously; Protease, lipase can be removed albumen impurity and the wax in the fiber; Can effectively the degrade cotton seed hulls of fabric face of zytase.Therefore, with the composite boiling that is used for COTTON FABRIC of this plurality of enzymes, the whiteness of the wetting property of the fabric that is obtained, removal of impurity and fabric is higher than the treatment effect of single alkaline pectase far away.Carbohydrate oxidase can be that substrate or glucose or other oligosaccharides are that substrate generates hydrogen peroxide with diastatic destarch product, be used for the bleaching of fabric, do not need to add in bleaching bath in addition hydrogen peroxide, the whiteness of fabric can satisfy the processing request of later process.The bleaching enzyme process of realizing fabric carries out, for the same bath of fabric desizing, kiering, bleaching multiple working procedure provides possibility, and shortened process and processing time, thus reduce cost.The pre-treatment enzyme process of COTTON FABRIC carries out, energy-conservation province consumption, and environmental friendliness is to substitute the Perfected process that traditional chemical is handled.
The specific embodiment
Embodiment 1: the kiering of COTTON FABRIC enzyme, destarch, bleaching one one bath two-step carry out
Fabric: textile poplin cloth (524/10cm of 15tex * 15tex * 283/10cm)
Technology: composite enzyme preparation (alkaline pectase 18%～23%, cellulase 10%～15%, α-Dian Fenmei 9%～12%, PVA digestive enzyme 10%～14%, proteinase 8 %～12%, lipase 10%～13%, carbohydrate oxidase 12%～14% and zytase 8%～13%) 1.2g/L, BHJ-1 high-efficiency refining agent 3g/L, waterglass (density 1.49/cm
3) 4g/L, sodium ethylene diamine tetracetate (EDTA) 5g/L; Bath raio 1: 20,55 ℃ of the first steps, pH8.0, effect 90min, in 95 ℃ of second steps, pH 11.0, effect 120min.
The result:
| The enzyme process boiling | |
| Whiteness/Wh | 86.25 |
| Capillary effect/cm | 12.33 |
| Pectin clearance/% | 87.39 |
| Cotton seed hulls removes rate/% | 70 |
